Throw distance
Throw distance is the distance measured from your projector’s lens to the screen. This is an
important calculation in any projector installation as it determines whether or not you have
enough room to install your projector with a desired screen size and if your image will be of the
right size for your screen.
you can quickly estimate the throw distance by taking the horizontal width of the screen and
multiplying it by the lens throw ratio. The result of this calculation tells you "roughly" how far back
the projector should be positioned from the screen in order to project a focused image large
enough to fill the screen. For example, using a 0.75:1 lens, throw distance would roughly be 0.75
x screen width.
IMPORTanT: Once you determine the type of lens and screen size you’re going to use,
calculate the precise throw distance using the formula or graphs located in appendix D. Due to
lens manufacturing tolerances for lens focal length, actual throw distance can vary ±5% between
lenses described as having the same throw ratio.
